[bamboo]

I do not know if the algae beginning to grow on this rock in my tank is good or bad? Any information is appreciated.

Thanks

nothing wrong with that algea green is good brown is bad lol

some fish, crabs, urchin's will all love to eat that green stuff
you need to keep it under control though, as long as it doesnt go mad ull be fine
